I created a web project in eclipse with database connection using mysql and for connection I used the following code :

public Connection dbConnect() throws Exception{
System.out.println("Listing all table name in Database!");
// strConnect = "Provider=SQLOLEDB.1;Integrated Security=SSPI;Persist Security Info=False;Initial Catalog=" & gDatabase_Name & ";Data Source=" & gServer_name
// gADOConnection.Open strConnect

Connection con=null;
String url = "jdbc:mysql://localhost:3306/";
String db = "employee";
String driver1 = "com.mysql.jdbc.Driver";

String user = "root";
String pass = "welcome";
try{


Class.forName("com.mysql.jdbc.Driver").newInstance();
con=DriverManager.getConnection ( url+db,user,pass );


System.out.println("end of testDbconnect");

}catch(Exception e){

e.printStackTrace();

}

return con;

}




}



I is running fine but when I made war of it and deployed on tomcat its not connecting to database.
Can anyone tell me the reason? Why its happening so?

What error does it give you? If it's driver not found, can you confirm the database driver is in your Tomcat classpath?
